The establishment and adjustment of HSR fare is based on clauses in appendix 5: "fare standards and the adjustment timing and methods of HSR fares" in the HSR Establishment and Operation Contract. According to regulations, THSRC should set a ticket rate (FB) in consideration of the government-approved standard rate (FG). In addition, MOTC will promulgate the HSR fare results on April 1st of each year after evaluating FG with the reference of Taiwan's GICP trend.
Looking at MOTC records, FG announ-ced on Dec. 28, 2006 during the opening year of Taiwan High Speed Rail equaled NT$ 3.655/person. This number was under the reference of 2005 GICP in Taiwan. In 2009 and 2013 in which Taiwan's annual GICP reached adjustment standard, MOTC announced FG fluctuations of NT$ 3.875/person and NT$ 4.009/person respectively. Regarding the FG this year (2015), the GICP in 2014 was 1.20% and the accumulated GICP since the last adjustment (2013) was 2.00%, both FG did not reach the adjustment standard ±3%. Therefore, the FG in 2015 will remain NT$ 4.009/person.
